Correct. And I strongly suspect they are wildly pumping out news about him to narrow the juror pool to people who do live under rocks.
The other option is that jurors lie about their bias, which opens them up for legal consequences.
His defense, in any case, has a very difficult task - they need to be able to somehow communicate him being innocent against stacked charges OR paint him light that the rest of us see that leans them towards Jury Nullification.
My hope is that potential jurors hide their bias, which isn't easy, but gives him the best chance.
